1) This makes lwsws run a parent process with the original permissions.
But this process is only able to respond to SIGHUP, it doesn't do anything
else.
2) You can send this parent process a SIGHUP now to cause it to
- close listening sockets in existing lwsws processes
- mark those processes as to exit when the number of active connections
on the falls to zero
- spawn a fresh child process from scratch, using latest configuration
file content, latest plugins, etc. It can now reopen listening sockets
if it chooses to, or open different listen ports or whatever.
Notes:
1) lws_context_destroy() has been split into two pieces... the reason for
the split is the first part closes the per-vhost protocols, but since
they may have created libuv objects in the per-vhost protocol storage,
these cannot be freed until after the loop has been run.
That's the purpose of the second part of the context destruction,
lws_context_destroy2().
For compatibility, if you are not using libuv, the first part calls the
second part. However if you are using libuv, you must now call the
second part from your own main.c after the first part.
This adds a context creation-time member that points to something
that should be freed when the context is destroyed.
It's in preparation for context deprecation, when a context might
be destroyed asynchronously... a related external with the
lifetime of thee context should also be freed at that time.
Adapt lwsws to use it with the context "strings" (also used for
aligned structs created by the config) allocation.
Actually lwsws doesn't need his own protocol handler even for http
any more. The default http handler in lws should do everything.
Move the cgi routing into lws default http protocol handler, and
delete lwsws one. Remove all protocols from lwsws so the lws
default one gets used.
With this, and the earlier move of lejp into lws, lwsws itself
becomes 15.5KB of x86_64 (mainly conf parsing).

If OOT lws plugins will be packaged as separate projects,
they're going to want to install their plugins somewhere
that makes sense for the package instead of one big lws
plugin dir.
This patch changes info to have a const char ** to a NULL
terminated array of directories it should search for
plugins. lwsws knows about this and you can add to the
dir array using config fragments like
{
"global": {
"plugin-dir": "/usr/local/share/coherent-timeline/plugins"
}
}
if the config fragment in /etc/lwsws/conf.d/ is also managed by the
package with the plugin, it can very cleanly add and remove itself
from lwsws based on package install status.

This
1) fixes the vhost changes on master
2) works around the ah pool changes
3) fixes some other build problems that appeared
4) hacks out physical flow control for internal streams
5) updates the advertised protocol to h2 needed by, eg, chrome 51
That gets it able to serve small (<4K, ie, one packet) files over http2

This adds support for dynamically loaded plugins at runtime, which
can expose their own protocols or extensions transparently.
With these changes lwsws defaults to OFF in cmake, and if enabled it
automatically enables plugins and libuv support.

This makes a start on the LibWebSockets WebServer.
The app cmake build support and JSON config parsing are implemented and
the app can start, create the vhosts, listen and serve file:// mounts on
them.
